Portfolio overview

Mitsubishi Gas Chemical Company, Inc. has been granted 808 US utility patents between 2015 and 2025, placing Mitsubishi Gas Chemical Company, Inc. at rank #555 across all assignees tracked by PlainPatent. This portfolio spans 137 distinct Cooperative Patent Classification (CPC) subclasses, averaging 12.6 claims per patent with primary concentration in C08G (MACROMOLECULAR COMPOUNDS OBTAINED OTHERWISE THAN BY REACTIONS ONLY INVOLVING UNSATURATED CARBON-TO-CARBON BONDS). As a Foreign Corporation, Mitsubishi Gas Chemical Company, Inc. is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Mitsubishi sits between Sony Mobile Communications Inc. (815 patents, rank #551) and Mandom Corporation (803 patents, rank #559) - the closest US assignees by grant volume. The composite Innovation Score of 61.5/100 blends portfolio volume, filing velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.

Filing cadence tells the strategic story. Between 2020 and 2025 the company received 404 grants, compared with 404 in the 2015–2019 window, a +0% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. The Foreign Corporation classification further shapes interpretation, since corporate, government, and individual filers pursue patents for materially different reasons.

Claim depth and technology breadth together indicate competitive posture. Mitsubishi Gas Chemical Company, Inc.'s 12.6 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a diversified footprint across 100+ CPC subclasses spreads risk across many technology fronts. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Mitsubishi Gas Chemical Company, Inc. against peers pursuing similar technology classes.
